The Study of Submerged floating tunnel characteristic under the wave conditions

Abstract

A large Submerged floating tunnel is studied at the many projects in the world. But there are many problems for the construction at the real sites.In Japan, investigation on the development of the Submerged floating tunnel technology has been started from 1990. This paper deals with the wave force characteristic to the tunnel with experiments (2-D channel) and numerical calculation by means of boundaly element method. From obtained results, the most important thing is snap force control under the large wave height.And numerical calculation of the wave force to the tunnel is good agreement with the experimental results.
